see, i am encountering that in my other game all the time.
I am up vs a very strong dominion and using dozens of priests preaching.
I am always -10 dominion before battles and -10 after battles.
But my dozens inquisitor priests assure me positive dominion many a times for actual battles.


Say you have +2 dom when you order to attack.
Then preachers change it to -1 e.g.
Then the battle happens at -1.
Then your temples put your dominion back to say +3.

Thats the mechanic.
It doesnt matter what the dom was the turn before the battle.
The actually dominion after preaching only matters for battles and is not visible as such on the map since is altered every time by normal dom spreads.
That way,you never can be 100% certain when odering vamps to attack,unless you either got very high dominion before preaching or are sure enemy hasnt preaching in that province or bring lots of you your own preachers.
